The patent is for "peripheral treatment for head-mounted displays," which allows images to be projected into your eye, says Bilton.

Now, just because Apple has a patent doesn't mean it's going to do anything. It is constantly researching new technology and patenting it. Those patents are proving to be quite handy in the smartphone wars.

However, in 2010, Apple hired Richard DeVaul, whose work at MIT focused on wearable computers. DeVaul was reportedly working directly under Jony Ive in a secret lab that only seven people knew about.

But DeVaul moved to Google in 2011, which might mean that Apple's not as serious as Google is about the technology.
